Telusa Veainu has been called into the Crusaders from the Highlanders to cover a wing shortage.
Zac Guildford's self-imposed break from the Crusaders, and the hamstring injury to New Zealand sevens player Kurt Baker, has left Todd Blackadder's team short of wings before the season has started.
Veainu, a member of the Canterbury ITM Cup team, was in the Highlanders wider training squad but has been called in by Blackadder on a short-term contract and been named in the reserves to play the southerners at a pre-season match in Oamaru on Friday.
Canterbury's Johnny McNicholl has recovered from a back injury and takes his place on the left wing.
All Blacks Wyatt Crockett, Luke Romano and Israel Dagg also return after missing the narrow defeat by the Hurricanes in Timaru.
